Reverse IP Lookup
Enter a domain to find other domains hosted on the same IP address. Useful for web reconnaissance and identifying shared hosting environments.
How to Use the Reverse IP Lookup
- Enter a domain name (e.g., example.com) in the input field.
- Click 'Lookup' or press Enter to start the reverse lookup.
- View the resolved IP address and any domains found on that IP.
- Copy individual domains or all results at once.
About Reverse IP Lookup
A reverse IP lookup resolves a domain to its IP address and then queries DNS PTR records to find other domains pointing to the same server. This is valuable for penetration testers to map the attack surface of a target, identify co-hosted applications that may share vulnerabilities, and understand the hosting infrastructure. Shared hosting environments often host multiple websites on a single IP, and compromising one can sometimes lead to lateral movement to others.
Frequently Asked Questions
A reverse IP lookup finds all domain names that resolve to a given IP address. It works by resolving the input domain to an IP, then querying reverse DNS (PTR) records for that IP.
It helps identify shared hosting environments where multiple sites share the same server. If one site is compromised, others on the same server may be at risk. It also helps map the full attack surface of a target organization.
